Hotel amenities these days are as much a ploy to get you to gush about them to your friends back home as they are to make your stay comfortable.

This list of over-the-top hotel amenities is worth bringing up because each is a rare one-off, not available in all sizes.

1. Choice of 20 Fender guitars

Who needs an in-room iPod, when one of 20 Fender guitars is available for free at Chicago's Hard Rock Hotel?

Although guests do have to put down a credit card (in case they start to channel Pete Townshend's guitar-smashing antics), they can keep their chosen ax bedside until such time as they either take their band on the road or check out.

Choices range from a $1,600 Stratocaster to classic Telecasters and bass guitars.

Also available are floor amps and Nixon headphones that will vprevent renditions of "Freebird" from rocking out other guests.

Those that don't know a "G" chord from a "C," can tune into a streamed 70-minute lesson from guitar instructor Rico Monaco.

The hotel now offers a similar program for DJ mixers in addition to guitars.

Taking inspiration from the historic British concession where it's located, The Ritz-Carlton, Tianjin is built to resemble an ancient British palace.

And what European palace is complete without a horse-drawn carriage and uniformed horseman?

Branding itself as a wedding hotel, the Ritz offers an extravagant "royal wedding package" that includes a Rolls Royce grand entrance, free-flowing Champagne tower, royal-themed cake and a ride on the carriage.

Non wedding guests can enjoy a 30-minute ride on the carriage around the former British concession too - for the princely sum of RMB50,000 ($8100).

At Nashville's Gaylord Opryland Resort & Convention Center, a monster hotel with 2,882 rooms, waterfalls, indoor rivers, daily light shows and more tropical vegetation than Biosphere 3, guests can opt for a rousing "Rise and Shine" wake-up call from a Who's Who of country music stars, including Vince Gill, Trace Adkins, Kellie Pickler and Wynonna Judd.

Guests might even bump into them in the flesh at the adjoining Grand Ole Opry stage, a Nashville institution since 1925.

In the basement of the Sunset Marquis Hotel in California is a professional recording studio that attracts some of the biggest names in showbiz, including Katy Perry, Tom Hanks, Christina Aguilera, Aerosmith and Clint Eastwood

The Nightbird studio handles tracking, editing and mixing with state-of-the-art technology and a staff of engineers.

Every couple that checks into Namale Resort and Spa on Fiji's Vanua Levu island is "kidnapped" at some point during their stay and taken to a surprise four-course picnic somewhere on the lush resort's 212 hectares.

Sometimes it's next to a waterfall, sometimes in a cave, sometimes on a private deck overlooking a blowhole in the Koro Sea. Guests never know when they will be summoned.

Four Seasons Resort Landaa Giraavaru at Baa Atoll, Maldives -- a UNESCO World Biosphere -- provides guests with a direct line to any manta rays in the area.

Well, almost.

Guests signed up for the "Manta-on-call" service during the manta ray peak season -- June to November -- will receive the latest sightings of manta rays in the area and be taken away on a speeding boat to the location.

At Vancouver's tiny Hotel Georgia and some other Rosewood's city hotels, there's no need to monitor perfume bottles to make sure they're less than 100 milliliters because there's no need to even pack them.

A white-gloved fragrance butler bearing 10 fragrances (five for him and five for her) on a silver salver will knock on your door within minutes of you notifying the concierge your wrists need spritzing.

Some selections can only be found in a specific hotel, for example Hermes Eau des Mervailles at The Carlyle in New York or Guerlain L'Instant de Guerlain at Rosewood Sand Hill in California.
